Abstract

A piercing piston (8) is disposed in a housing (2) and can be acted upon by spring force. The piston comprises a detent recess (19) for the introduction of a detent (10) and can be transferred from an initial position into an actuating position releasing a pressure reservoir. The piercing piston is divided in construction, with a piston portion (11) which can be locked by the releasable detent and a piston head (12) which is movable in relation to this piston portion and comprises a surface for the action of pressure. The piston portion can be twisted about the longitudinal centre axis (22) of the piston.
